We have a testing server with its own domain name. We don't want any email to be sent from this domain. We don't want any email to be received on this domain.

Is it ok to remove the MX record from the DNS?

Yes, an MX record is there only for incoming mail.

While this is true, MX records are also used by some spam detecting mechanisms. So if you try to send outgoing mail to some other server, it might reject you because of missing or incorrect DNS entries, including your MX record (is there an MX record for the domain you are trying to send from, if so, does it point to the server you are sending from ...) –  Isaac Apr 16 '13 at 20:11

Isaac - The OP stated that he doesn't want to send OR receive email from or to this server. In addition, any spam mechanism that uses the MX record for a domain (instead of the SPF record for the domain) is doing it wrong. –  joeqwerty Apr 17 '13 at 4:26
